I As shown, twelve of these whereby the depression of a single key will cause keys 8 set blocks for the digits from 1 to 9, in- 55 may be controlled by still other keys.

The keys 8 are carried upon spring-raised stems as shown in Fig. 2. The stems are extended on the lower collar memcross rails I5 which, in turn, are supported by rollers I6. The rollers I6, in turn, rest upon angle members I7, which, in turn, are mounted The carriage I4 contains The first set of translating interponents 2| in the carriage I4, as shown in Fig. 3, consists simply of straight-through push rods or interponent members as shown in Fig. 6. Accordingly, the depression of a key 8 carries downward a member I2 and, if the carriage I4 is in its lefthand position, (Fig. 3), a single interponent member 2| is depressed to actuate a single Bowden wire 5, a single setting lever 4 (Fig. 1) and set a single punch-blocking member 3, according to the single unit code.

If the carriage I4 is moved to its mid-position, as shown in Fig. 3, another set of translating members 22 is brought into play between the members I2 and the Bowden wires 5. This set of translating members 22 is shown in further detail in Fig. 8. There are provided ten input members for the ten digits shown by the numbers in Fig. 8, of which six extend through to the bottom of the carriage, as shown.

In Fig. 8, the interponent 22 for the number while its upper end cooperates with the key, the lower end mid-position, depression of the 9 key sets a punch column in the sixth ment for the digit 9 in the upper field as indicated in the above-mentioned patent.

The 9 interponent carries a flag member 23 as shown in Figs. 3, 4, and 8.

The interponent member for the number '7, cooperating with the member I2 carried by the 7 key, likewise is extended through from top to bottom of the carriage I4, also with a displacecard as required for code above disclosed.

The interponent member for the digit 8, which cooperates with the 8 key, as shown in Fig. 8,

Similarly, by movement of the carriage I4 to rods I2 and the 26 are shown in for setting gags in the lower field. In the operation of a punch device of this invention, the

the carriage I4 may be set in mid-position by lever 21 whereupon punchblocking members for the upper field may be set and, if the upper field only is to be used, the carriage may remain in its mid-position and the punch may be operated by the trip key at the close of each travel of the carriage.

by lever 21 and the appropriate punch-blocking members set for the desired data in the lower field of the card. Thereupon, the punch may be operated to punch the desired records in both upper and lower fields, whereafter the punch carriage I may be returned to the start position by the lever 29, which depresses the clearing roll 3I into engagement with the release slides 32, thereby releasing the punch blocking members previously set in both upper and lower fields.

By the device of this invention there is thus cards according to either a single unit or multiunit code in upper or lower fields at the operator's desire.

While there is above disclosed but a single embodiment of the device of the invention, it is possible to produce still other embodiments without departure from the inventive concept herein disclosed, and it is therefore, desired that only 7 such limitations be imposed upon the appended claims as are stated therein or required by the prior art.

What I claim as new and desire to secure by Letters Patent is:

1. In a punch mechanism, the combination of a keyboard, a punch and punch setting mechanism controllable thereby, and a plurality of coding mechanisms cooperating therebetween, said keyboard mechanism comprising key-tail-members positioned in a single line, said coding mechanism comprising a movable carriage having therein a plurality of sets of interponent members respectively comprising ofiset interponents and flag members.

2. In a card punch mechanism, the combination of a punch and punch setting mechanism including a die, a plurality of punches, a plurality of punch-blocking-members, a punch-blocksetting carriage and a plurality of flexible con-.

nections thereto, a keyboard comprising a plurality of keys having tails linearly positioned and a plurality of interponent systems cooperating between said key tails and said flexible connections, one of said sets of interponent members comprising push rods'linearly positioned between said key tails and said flexible connections, another of said sets of interponents comprising members extending from ten of said keys to six of said flexible connections, one of said interponent members having a transverse flag thereon and four of said interponent members having auxiliary flags thereon adapted to cooperate with said first mentioned flag and another interponent.

3. In a card punch mechanism, the combination of a punch and punch setting mechanism including a die, a plurality of punches, a plural- 5 ity of punch-blocking-members, a punch-blocksetting carriage and a plurality of flexible connections thereto, a keyboard comprising a plurality of keys having tails linearly positioned and a plurality of interponent systems cooperating between said key tails and said flexible connections, one of said sets of interponent members comprising push rods linearly positioned between said key tails and said flexible connections, another of said sets of interponents comprising members extending from ten of said keys to six of said flexible connections, one of said interponent members having a transverse flag thereon and four of said interponent members having auxiliary flags thereon adapted to cooperate with said first mentioned flag and another interponent, and another of said interponent members comprising a similar assemblage of members with the through extended interponent members adapted to cooperate with another group of six flexible connections.

4. A keyboard mechanism comprising a group of key members having aligned tail portions adapted to cooperate with a group of Bowden wire connecting members through interchangeable interponent systems, and another group of key members directly connected to Bowden wires.
